Product Description
M20 Dual Directional 4-Mic Array USB Microphone Module
The M20 is a board-level dual directional 4-mic array microphone module designed for fast OEM integration. A 4-microphone matrix with DSP beamforming captures two talkers on independent directional channels and delivers audio through USB Type-C and 3.5mm analog outputs simultaneously.
Core Selling Points
- USB Type-C + 3.5mm Dual Output: digital UAC1.0 and analog audio from a single 38mm x 38mm board.
- Dual Directional A/B Separation: ≥60° bidirectional pickup isolates two speakers and cuts off-angle voices by ≥12dB SPL.
- 4-Mic Beamforming DSP: voice enhancement, noise suppression (≥20dB) and AGC give clear capture within 3m.
- Compact 38x38mm Board Level Design: a 53mm x 6mm mic strip that fits terminals, kiosks and displays.
